Solve the following system of equations algebraically<br> 3x-y=0<br> 5x+2y=22
Lyrx [107]

3x  -  y  = 0     ⇒   2(3x  -  y  = 0 )   ⇒   6x - 2y = 0

5x + 2y = 22  ⇒   1(5x + 2y = 22)   ⇒   <u>5x + 2y</u> = <u>22 </u>

                                                              11x         = 22

                                                                x          = 2

3x  -  y  = 0   ⇒   3(2) - y = 0   ⇒   6 - y = 0   ⇒   6 = y

Answer: x=2, y=6

F(x)=x^2+12x+7 f(x)=(x+_)^2+_ Rewrite the function by completing the square
Veseljchak [2.6K]

Answer:

f(x) = (x + 6)² - 29

Step-by-step explanation:

Given

f(x) = x² + 12x + 7

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² + 12x

x² + 2(6)x + 36 - 36 + 7

= (x + 6)² - 29, thus

f(x) = (x + 6)² - 29
